Just to be clear, I wasn't requesting that *you* make '-k' the default *
within* 'dhcpcd'.  I was simply quoting a request I'd made to the
NetworkManager and Arch Linux bug trackers in the hope that *they* would
terminate 'dhcpcd' differently.

Thanks for making a patch that'll fix this problem at your end.  There would
be plenty of other affected users, most of whom probably don't understand
what's causing it.  For the sake of privacy, I'll send the TCP dump to you
in a separate email.
